java - Android媒体录制错误启动失败-19 runTimeException

Question

我的媒体录制遇到问题。我正在尝试使用前置摄像头进行录制。这给了我一个错误(但预览正常)。每当我使用后置摄像头时，一切都正常，我认为这很奇怪。问题可能是什么以及解决方案是什么？我的代码和错误如下所示。

编辑。使用 VGA 前置摄像头录制似乎不起作用。这怎么可能？尽管可以使用 HTC 相机应用程序进行录制。

提前感谢您。

protected void startRecording() throws Exception 
{
    mrec = new MediaRecorder();
    mCamera.unlock();

    mrec.setCamera(mCamera);


    mrec.setVideoSource(MediaRecorder.VideoSource.CAMERA);
    mrec.setAudioSource(MediaRecorder.AudioSource.MIC); 

    mrec.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));
    //mrec.setPreviewDisplay(surfaceHolder.getSurface());

    File picDirectory = new File(Environment.getExternalStorageDirectory() +"/TrouwApp");
    picDirectory.mkdirs();

    File mediaStorageDir = new File(Environment.getExternalStorageDirectory() +"/TrouwApp", "Videos");

    // Create the storage directory if it does not exist
    if (! mediaStorageDir.exists()){
        if (! mediaStorageDir.mkdirs()){
            Log.d("MyCameraApp", "failed to create directory");
        }
    }

    mrec.setOutputFile( mediaStorageDir.getPath() + File.separator  + date + "_" + videonr+ ".3gp"); 

    mrec.prepare();
    mrec.start();//line 136

    Log.d(TAG, "Recording started!!");
}

添加到 list 的行:

<uses-feature android:name="android.hardware.camera" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Answer 1

找到了解决方案。由于我使用的是前置摄像头，因此我需要从前置摄像头获取摄像机配置文件。我通过这样做实现了这一点:

mrec.setProfile(CamcorderProfile.get(1, CamcorderProfile.QUALITY_HIGH));

而不是这个:

mrec.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));
